TPS2067D datasheet by Texas Instruments

TPS2067D Frequently Asked Questions (FAQs)

• What is the maximum capacitive load that the TPS2067D can drive?
  The TPS2067D can drive up to 10,000 pF of capacitive load, but it's recommended to limit it to 4,700 pF for optimal performance.
• How do I ensure the TPS2067D switches on and off quickly?
  To ensure fast switching, make sure to use a low-ESR output capacitor (less than 100 mΩ) and keep the input capacitance low (less than 100 pF). Also, use a pull-up resistor on the EN pin to ensure a fast rise time.
• What is the minimum input voltage required for the TPS2067D to operate?
  The TPS2067D can operate with an input voltage as low as 2.7V, but it's recommended to use a minimum of 3.0V for optimal performance.
• Can I use the TPS2067D as a high-side switch?
  No, the TPS2067D is a low-side switch, meaning it can only switch the ground connection of a load. It's not suitable for high-side switching applications.
• How do I protect the TPS2067D from back-EMF when switching inductive loads?
  Use a flyback diode (such as a 1N4148) in parallel with the inductive load to protect the TPS2067D from back-EMF. This will prevent voltage spikes from damaging the device.
